A man has admitted murdering his estranged wife and her partner on New Year's Day.
Helen Hancock, 39, and Martin Griffiths, 48, were found stabbed to death at a house in Duffield, Derbyshire, in the early hours of 1 January.
Rhys Hancock, of Portland Street in Etwall, Derbyshire, pleaded guilty at Derby Crown Court to both murders.
The 40-year-old will be sentenced at a date to be fixed.
The court heard Hancock called police at about 04:20 GMT to say he was at his former marital home and admitted murdering Ms Hancock and her lover Mr Griffiths.
Police officers found the bodies of PE teacher Ms Hancock and businessman Mr Griffiths in the house.
An inquest heard both had suffered multiple stab wounds and there was a blunt trauma injury to Ms Hancock's right eye.
'Wonderful mummy'
A close friend of Ms Hancock said she been "loving life" in the months leading up to the killings and had climbed Mount Snowdon with her new partner just days before they died.
Another friend described her as "a wonderful mummy to her three beautiful children" and "just a lovely, bright, positive person".
A friend of Mr Griffiths said he was "an absolutely brilliant dad" who was "passionate about his mountaineering".
A previous court hearing was told Mr Hancock had found out about his wife's new relationship on 26 December and it had caused him "some distress".
